Cutting margin of fixed finger with well-developed lobular basal tooth, followed by row of corneous scales to distal end. Inner and outer surfaces of fixed finger with rows of long setal tufts next to cutting margin. Carpus: dorsal margin with 2 proximal tubercles, median spine, distal spine longest, each tubercle or spine with small setae and terminal corneous scale, subterminal lobe well defined, pointed, with small corneous scales and setae. Inner surface with large tubercle, long setae next to dorsal margin. Outer surface with carpal ridge high, with small corneous scales.

Anteromesial region of third thoracic sternite abrupt, projecting between coxae of third maxillipeds, with scattered setae (Figure 7 C). Fourth thoracic sternite with anterolateral angles produced anteriorly, with scattered setae (Figure 10 A). Pleopods 2 – 5 absent. Anterolateral angle of second abdominal epimeron well defined, unarmed (Figure 10 B). Ventral angle of third abdominal epimeron well defined with small corneous scales apically. Ventral angle of fourth abdominal epimeron well defined, unarmed. Anterior margin of second abdominal epimeron almost straight (Figures 7 D, 10 B). Uropods well developed, wide (WU / HWT = 1.04). Telson divided by longitudinal suture. Anterolateral and posterolateral margins well differentiated. Variations The areola can be subrectangular (n = 10), trapezoidal (n = 2) or rectangular (n = 1). The cardiac area varies from subrectangular (n = 9) to trapezoidal (n = 4). The palmar crest may appear rectangular instead of subdisciform. The anteromesial region of third thoracic sternite can be abrupt (n = 8) or tapered (n = 5). The anterolateral angle of second abdominal epimeron may present apical corneous scales instead of being naked as in the holotype. In most specimens, the ventral angle of the third abdominal epimeron is devoid of corneous scales. The uropods are narrow in a few specimens (n = 2).

03B287D3FFDA771FFE484D7DD4986CE9.taxon	etymology	Etymology The specific epithet ‘ abrupta’, from the Latin abruptus, refers to the abrupt third thoracic sternite of the species.	en	Marçal, Ingrid Costa, Páez, Fernanda Polli, Silva, Priscila Frazato Da, Souza-Shibatta, Lenice, Teixeira, Gustavo Monteiro (2021): Cryptic diversity among populations of Aegla Leach, 1820 (Decapoda: Anomura: Aeglidae) from Tibagi River basin, Paraná state, Brazil, with descriptions of three new species.

03B287D3FFDA771FFE484D7DD4986CE9.taxon	distribution	Distribution The new species has been collected in three watercourses within the Tibagi River subbasin, Paranapanema River basin. These watercourses are located in the city of Ortigueira, Paraná state, Brazil. Conservation status We suggest that Aegla abrupta sp. nov. be assigned as ‘ Vulnerable’ (VU) under criteria B 1, B 2 ab (iii) as defined by the IUCN (2019). This species has been recorded in three localities (B 2 a) and the known extent of occurrence is estimated to be less than 500 km 2 (B 1). The streams where the specimens of Aegla abrupta sp. nov. were found are in agricultural and urbanised areas (B 2 b (iii )).	en	Marçal, Ingrid Costa, Páez, Fernanda Polli, Silva, Priscila Frazato Da, Souza-Shibatta, Lenice, Teixeira, Gustavo Monteiro (2021): Cryptic diversity among populations of Aegla Leach, 1820 (Decapoda: Anomura: Aeglidae) from Tibagi River basin, Paraná state, Brazil, with descriptions of three new species.

03B287D3FFDA771FFE484D7DD4986CE9.taxon	discussion	Remarks Aegla abrupta sp. nov. can be separated from its congeners, mainly by, among other characters, subrostral process well developed (undeveloped in A. strinatii), occupying proximal half of subrostral margin (on proximal third of subrostral margin in A. lata, A. jacutinga, Aegla santosi sp. nov. and Aegla nanopedis sp. nov., and occupying median portion of subrostral margin in A. jaragua); anterior and posterior margins of subrostral process forming acute angle (right angle in A. lata and A. jacutinga, and obtuse angle in A. jaragua, Aegla santosi sp. nov. and Aegla nanopedis sp. nov.); orbital and extra-orbital sinuses deep (shallow in A. odebrechtii); epigastric prominences pronounced (poorly pronounced in A. lata and A. jacutinga); protogastric lobes pronounced (poorly pronounced in A. odebrechtii, A. lata, A. jarai and A. jaragua); cervical groove trapezoidal (U-shaped in A. lata and Aegla nanopedis sp. nov.); subterminal lobe of carpus well defined, pointed (poorly defined in A. strinatii); outer surface of carpus with carpal ridge high (low in A. jacutinga); dorsal margin of carpus and merus of second pereiopods with small tubercles with terminal corneous scale (with distal spine followed by tubercles decreasing in size proximally in A. jarai); ventral margin of merus of second pereiopods with small tubercles with terminal corneous scale (one or two small spines in A. castro and A. schmitti); anteromesial region of third thoracic sternite abrupt (tapered or truncate in A. lata, truncate in A. jaragua, and tapered in A. jacutinga, Aegla santosi sp. nov. and Aegla nanopedis sp. nov.); anterior margin of second abdominal epimeron almost straight (concave in A. castro and A. schmitti and slightly concave in A. jacutinga); uropods wide (narrow in A. lata and A. jaragua). Our Bayesian tree based on the COI mitochondrial gene (Figure 6) recovered Aegla abrupta sp. nov. as the sister species to Aegla nanopedis sp. nov., and both clustered in the same subclade as A. jacutinga. The interspecific genetic distances (Table 2) reinforce the relationships evidenced in the Bayesian analysis.	en	Marçal, Ingrid Costa, Páez, Fernanda Polli, Silva, Priscila Frazato Da, Souza-Shibatta, Lenice, Teixeira, Gustavo Monteiro (2021): Cryptic diversity among populations of Aegla Leach, 1820 (Decapoda: Anomura: Aeglidae) from Tibagi River basin, Paraná state, Brazil, with descriptions of three new species.
